WAS IN EIGHT CAR CHAIN REACTION COLLISION, WHERE I WAS THE 7TH OF 8 CARS. THEREFORE, I HAD SEVERE FRONT-END DAMAGE AND EVEN WORSE REAR-END DAMAGE. I ACTUALLY HIT THE CAR IN FRONT WITH MY OWN FORCE (2 ON SCALE OF 1-10) AND THEN AGAIN WHEN THE CAR BEHIND HIT ME. THE SECOND HIT WAS 10 ON A SCALE OF 1-10. THE CARS WHERE GOING OVER 20 MPH (ESTIMATED) AT TIME OF ACCIDENT.*AK FRONT AIRBAGS DID NOT DEPLOY. ACCORDING TO THE TOYOTA MANUAL THEY SHOULD DEPLOY AT 15MPH OR MORE, FORCE IS GREAT ENOUGH, OR WHEN VEHICLE INSIDE PRESSURE CHANGE IS GREAT ENOUGH. (NOTE: WHEN THE CAR WAS HIT IN THE REAR, THE ENTIRE REAR WINDOW SCHATTERED, THEREBY, CAUSING GREAT PRESSURE CHANGE.) ACCORDING TO THE BODY SHOP WHICH GAVE ESTIMATE FOR REPAIR THE AIRBAGS SHOULD HAVE DEPLOYED ACCORDING TO THE FRONT-END DAMAGE ALONE. (WE HAVE DIGITAL PICTURES OF THE VEHICLE AND CAN SEND THEM.)
